Canal Transportation After Instrumentation Utilizing Different Endodontic Access Design; A Comparative Study With Micro-Ct., Travis Moore
Graduate Theses, Dissertations, and Problem Reports (ETD)
Introduction Access cavity design is known to affect theefficiency of instrumentation. Canal transportation occurs primarily in the apical region and to the outside of curvature when dentin is removed in a single direction. The goal of all cleaning and shaping procedures is to preserve the original root canal anatomy while removing sufficient amounts of injured pulp tissue, microorganisms, toxins and instrumentation byproducts. It is understood that the desired shape of the finished root canal is a continuous tapering funnel from the coronal to the apex. The aim of this study is to construct detailed three-dimensional images of root canal systems …
Integrating Microscale Enzyme And Lectin Reactions Using Nanogel Assisted Capillary Electrophoresis, Srikanth Gattu
Integrating Microscale Enzyme And Lectin Reactions Using Nanogel Assisted Capillary Electrophoresis, Srikanth Gattu
Graduate Theses, Dissertations, and Problem Reports (ETD)
Protein glycosylation is one of the most prevalent post-translational modifications which plays an important role in determining the structure, stability, and function of proteins. Changes in glycosylation patterns are a hallmark of cancer and other diseases. Characterizing glycosylation is difficult because these structures vary in their linkage and monomer sequence, which gives rise to vast microheterogenity that could affect the function of the molecule. A novel method using capillary gel electrophoresis by integrating microscale enzymes and lectin reactions in the capillary was developed to verify glycan structure by analyzing monosaccharides. Capillary electrophoresis (CE) improves upon conventional methods of glycan structure …
The Principles And Rhetoric Of Autarky: Debate And Decision-Making In Early Colonial Kenya, Ian Michael Ferguson
The Principles And Rhetoric Of Autarky: Debate And Decision-Making In Early Colonial Kenya, Ian Michael Ferguson
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study seeks to understand the decision-making process of the colonial government of the East Africa Protectorate by articulating the principles of autarky: financial independence, development, and effective occupation. The principles of autarky, which are both goal and process for the colonial government, strove to bring that government to a state of self-sufficiency, or autarky. These principles created their own rhetoric within official correspondence which dominated the decision-making process. By looking at three different periods, Foreign Office control, the transition to Colonial Office responsibility, and the Soldier Settlement Scheme of 1919, the importance of the principles and rhetoric of autarky …

Graduate Theses, Dissertations, and Problem Reports (ETD)
In this study, the modified double power law (MDPL) model is used to determine the tensile creep of concrete at an early age based on the ASTM C1581 restrained shrinkage ring test. Three concrete mixes using Ordinary Portland Cement (OPC) were tested. The three concrete mixes were cast, and each underwent the ring tests up to cracking. Mechanical properties of concrete at the age of 1, 3, 7, 14, and 28 days were tested to find the compressive strength, tensile strength and Young’s Modulus of concrete. The strength tests results were obtained from both 4x8 inch and 6x12 inch cylinders. …
Understanding The Impact Of Stimulation Treatment On Gas Production From A Horizontally Drilled Marcellus Shale Well, Matthew Dean Carl Perrella
Understanding The Impact Of Stimulation Treatment On Gas Production From A Horizontally Drilled Marcellus Shale Well, Matthew Dean Carl Perrella
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Marcellus shale is one of the largest unconventional gas shale plays in the United States. It underlies much of Pennsylvania, West Virginia, and New York and even extends under Lake Erie and into Canada. The most effective methods to produce from this play is to drill horizontally into the shale formation and use hydraulic fracturing. Hydraulic fracturing creates pathways for the hydrocarbon to flow from the shale into the wellbore. These lateral sections of the well are typically completed from toe to heel over a number of stages using a plug and perforate method.;This research focuses on a Marcellus …

Temporal Bisection And Effects Of D-Amphetamine Administration In Lewis And Fischer 344 Rats, Marissa Turturici
Temporal Bisection And Effects Of D-Amphetamine Administration In Lewis And Fischer 344 Rats, Marissa Turturici
Graduate Theses, Dissertations, and Problem Reports (ETD)
Temporal control concerns the discrimination of intervals of time. Individuals with various psychological disorders have shown differences in temporal control when compared to control populations. It is unknown whether and how temporal control might be linked with impulsivity, another measure that predicts problem behavior such as attention-deficit/hyperactivity disorder. Because Lewis (LEW) rats reliably show greater impulsive choice relative to Fischer 344 (F344) rats, the present study examined responding in these two strains under a temporal-bisection procedure that assesses temporal control. In the temporal-bisection procedure, rats are trained to discriminate between two durations. Intermediate durations are subsequently presented to determine the …

Inclusion Of 9 Mm Firearm Type Using Quantitative Class Characteristics, Young Wang
Graduate Theses, Dissertations, and Problem Reports (ETD)
The results of a data set of five models of 9 mm Luger caliber handguns suggest an algorithm such as the square of the Mahalanobis Distance as a step towards the creation of an electronic class characteristic database for cartridge cases to supplement the currently existing General Rifling Characteristic (GRC) database for bullets. The algorithm was validated using both hold-one out cross validation as well as on an entirely independent set of ground truth known cartridge cases which were blindly classified to mimic case work. A method for determining an objective threshold for inclusion onto a list for an investigator …
Standing In The Shadow Of Empire: Ideology In The Path To West Virginia Statehood, Kristen L. Wilkes
Standing In The Shadow Of Empire: Ideology In The Path To West Virginia Statehood, Kristen L. Wilkes
Graduate Theses, Dissertations, and Problem Reports (ETD)
An empire of industry moved through West Virginia prior to the US Civil War, and saw a breed of capitalists and politicians who acquired control of land through purchase and through patent, developed control of the vote through industrial political influence, and encouraged the West Virginian to separate from an eastern Virginian society based in planter-elite agrarian society. The West Virginian who believed that self-sufficiency and subsistence farming could sustain his family saw his vote for statehood and separation from the Old Dominion transformed into an industrial coup. Land slowly but steadily slipped away from the hands of the mountaineer …
Durability Of Gfrp Composites Under Harsh Environments: Effect Of Ph And Temperature, Maria Martinez De Lahidalga De Lorenzo
Durability Of Gfrp Composites Under Harsh Environments: Effect Of Ph And Temperature, Maria Martinez De Lahidalga De Lorenzo
Graduate Theses, Dissertations, and Problem Reports (ETD)
In recent years, demand for Fiber Reinforced Polymer (FRP) Composites as a substitute of conventional materials has increased because of certain inherent advantages of FRPs over conventional materials such as concrete or steel. However, FRPs are also susceptible to degradation under both physical and chemical aging. To evaluate glass FRP composites aging behavior under harsh environments in a cost-effective manner, accelerated aging data are obtained under controlled lab environments, in short duration, to perform a correlation with data from naturally aged samples. Following the time-temperature superposition principle, the mechanical response in the field in a span of time of 75 …

Enhancing Online Security With Image-Based Captchas, Brian M. Powell
Graduate Theses, Dissertations, and Problem Reports (ETD)
Given the data loss, productivity, and financial risks posed by security breaches, there is a great need to protect online systems from automated attacks. Completely Automated Public Turing Tests to Tell Computers and Humans Apart, known as CAPTCHAs, are commonly used as one layer in providing online security. These tests are intended to be easily solvable by legitimate human users while being challenging for automated attackers to successfully complete. Traditionally, CAPTCHAs have asked users to perform tasks based on text recognition or categorization of discrete images to prove whether or not they are legitimate human users. Over time, the efficacy …

Using Incidental Teaching To Teach Mands To Children With Autism Spectrum Disorder, Katherine S. Robinson
Using Incidental Teaching To Teach Mands To Children With Autism Spectrum Disorder, Katherine S. Robinson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Children with autism display deficits in three core areas; communication, social interaction, and restrictive and repetitive behaviors. Deficits in communication often manifest in the form of maladaptive behaviors that serve to have the individuals needs and wants met. Additionally, children with autism may have difficulty generalizing learned skills to novel environments and with novel items. Naturalistic teaching procedures, such as incidental teaching, can promote generalization through the use of naturally occurring learning opportunities and reinforcers. The purpose of this study is to evaluate an incidental teaching procedure on the acquisition of both rate of manding behavior as well as a …
To Treat Or To Teach: Comparing Strategies To Reduce Escape-Maintained Behavior, Lucie M. Romano
To Treat Or To Teach: Comparing Strategies To Reduce Escape-Maintained Behavior, Lucie M. Romano
Graduate Theses, Dissertations, and Problem Reports (ETD)
Differential negative reinforcement of alternative behavior (DNRA) reduces escape-maintained challenging behavior, but can result in lost instructional time. Instructional time could be maintained through interventions like curricular revision (CR), but the efficacy of CR is less established. We compared DNRA and CR for 3 children with age-typical intellectual functioning whose challenging behavior was maintained by escape from academic tasks. During DNRA, we taught the child to appropriately request a different, mastered task. During CR, we broke the original task into simpler components until the child mastered each component, but still permitted escape following challenging behavior. Curricular revision resulted in less …
A Long Short-Term Memory Neural Network For Improved Twins' Voice Differentiation, Stallone Bruno-Ray Sabatier
A Long Short-Term Memory Neural Network For Improved Twins' Voice Differentiation, Stallone Bruno-Ray Sabatier
Graduate Theses, Dissertations, and Problem Reports (ETD)
Although successfully implemented in certain situations, the reliability of speaker recognition (SR) decreases due to speaker and channel variability present between enrollment and evaluation samples, as well as the available length of speech utterances. The issue of speaker variability becomes more pronounced when the number of speakers in the evaluation set increases, as there is a higher probability that two voices may sound more alike. The differentiation of intra-twin pairs' voices can be beneficial to general SR because inclusion can simulate this effect. This is due to the fact that their shared voice similarities are comparable to the potential inter-speaker …
